Disturbed sleep.

I woke up this moth while I was pottering around in the shed. It didn't seem too pleased. I went through my old book and found nothing matching the description. That always bugs me, especially with bugs.
In Dublin slang the word 'mot' means girlfriend. When I went back to the house for a mug of tea I had the following conversation with the Redhead.
"How was your gig last night?"
" Ah, it was good, the craic was ninety..... I think I found a new moth."
"Well, she's welcome to you."
Can any of you guys put a name to this one seeing as we now seem to be an item?
